  In manufacturing a mobile phone, there is a step of attaching a liquid crystal display panel to a housing with resin or the like as disclosed in Patent Document 2. Therefore, once the liquid crystal display panel is pasted and pasted, it is necessary to remove the adhesion, so that not only the liquid crystal display panel but also the front panel may have to be disposed of as a defective product. For this reason, in the process of attaching the liquid crystal display panel, since careful attention is required, workability is not good.

  Therefore, it is conceivable to adopt a mechanism for preventing deviation as seen in, for example, Patent Document 1, but it is necessary to use a special shape, and a general-purpose product cannot be used, so that the cost of the liquid crystal display panel increases. . That is, it is too costly as a cost for countermeasures against misalignment of the liquid crystal display panel.

  Therefore, a main object of the present invention is to provide a novel mobile phone.

  Another object of the present invention is to provide a mobile phone that can cope with a shift in the attachment of a liquid crystal display panel at a low cost.

  The present invention employs the following configuration in order to solve the above problems. The reference numerals in parentheses, supplementary explanations, and the like indicate the corresponding relationship with the embodiments described in order to help understanding of the present invention, and do not limit the present invention.

  A first aspect of the present invention is a mobile phone having a housing in which a display window is formed, and an LCD unit that is attached to the display window of the housing and has a colored portion having a predetermined color on the edge.

  In the first invention, a cellular phone (10: reference numerals exemplifying corresponding parts in the embodiment; the same applies hereinafter) includes a casing (C) in which a display window (32) is formed and a display window of the casing. And an LCD unit (22) in which a colored portion (26) having a predetermined color (black) is formed on the edge. Therefore, the display area (24) of the LCD unit is visually recognized through the display window. In addition, on the periphery of the LCD unit, a part of the formed colored portion can be seen from the surface of the display window, for example, for the purpose of preventing light from the backlight from leaking to the front surface. Further, printing (32) is formed on the edge of the display window, and the color of the printing is the same or similar to the color of the colored portion (black, dark gray, dark blue, dark brown, etc.). For this reason, even if the colored portion is looked through from the display window due to the deviation of the attachment of the LCD unit, it becomes inconspicuous due to the presence of printing of the same or similar color.

  According to the first aspect of the present invention, since the misalignment of the attachment becomes inconspicuous due to the presence of printing formed at the edge of the display window, the misalignment of the liquid crystal display panel can be dealt with at a low cost.

  The second invention is dependent on the first invention, and the colored portion is a black mask.

  The third invention is dependent on the first invention or the second invention, and printing is formed on the entire edge of the display window.

  According to the third aspect, since the frame is printed on the periphery of the display window, it is possible to make the vertical and horizontal shifts, the rotation shifts, and the like inconspicuous.

  A fourth invention is dependent on any one of the first to third inventions, and printing is formed on a side of the display window to which the LCD unit is attached.

  According to the present invention, since there is no conspicuous misalignment due to the presence of the printing frame, it is possible to provide a mobile phone that can cope with the misalignment of the liquid crystal display panel at low cost.

  The above object, other objects, features, and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

  FIG. 1 is an external view of a mobile phone 10 which is a kind of mobile terminal. Referring to FIG. 1, the mobile phone 10 has a straight shape and has a flat rectangular casing C. The display 12 is built in the housing C so that the LCD unit 22 (see FIG. 2) can be seen from the main surface side of the housing C. A key input device 14 composed of a plurality of keys is provided below the display 12. The housing C incorporates a processor called a CPU or a computer, and the display 12 and the key input device 14 are connected to the processor.

  The key input device 14 includes a call key and an end key, and also includes dial keys including a “0”-“9” key, a “*” key, and a “#” key. For example, key information (key data) operated by the user is input to the processor. When key information is input to the processor, an image is displayed on the display 12 in accordance with the key information.

  For example, while confirming the display 12, the user operates a dial key to input a telephone number, performs a voice call operation using the call key, and performs a call end operation using the call end key. In addition, the user turns on / off the power of the mobile phone 10 by pressing and holding the end call key.

  Note that an antenna and a wireless communication circuit for establishing a call state, a microphone and a speaker for making a call, and the like are not shown in FIG. Moreover, in the housing | casing C, a main surface is a front panel (cover), and can be removed.

  FIG. 2 is an illustrative view showing a configuration of the display 12. Referring to FIG. 2, the display 12 includes a substrate 20 and an LCD unit 22 provided on the substrate 20. The substrate 20 is provided with a terminal portion 28 for connection to other circuits (such as a display driver). The LCD unit 22 includes a display area 24, and a black mask 26 is formed in the periphery and the display range 24. The black mask 26 is also called a black matrix, and is formed in a lattice shape surrounding the color filters (three colors of red, green, and blue) in the display area 24, and improves the contrast of the display 12. The periphery of the LCD unit 22 is formed for the purpose of preventing light from a backlight (not shown) from leaking to the front surface. However, since the grid of the black mask 26 in the display area 24 is very small, it cannot be visually recognized normally.

  FIG. 3 is an illustrative view showing the upper side of the main surface of the housing C. FIG. A display window 32 is formed above the main surface of the housing C so that the LCD unit 22 can be seen from the front surface side. Further, a printing frame 30 is formed on the rear surface of the peripheral edge of the display window 32, and the printing frame 30 can also be visually recognized from the front surface side of the display window 32. Further, the color of the printing frame 30 is black (black) having the same hue or lightness and saturation as the black mask 26. However, in the drawings after FIG. 3, the print frame 30 is illustrated with a pattern in order to avoid obscuring due to the overlap with the black mask 26.

  FIG. 4 is an illustrative view showing an example of a cross section in a state where a display is attached to a housing. With reference to FIG. 4, the display window 32 is formed by fitting transparent tempered glass into the housing C, and the printing frame 30 is printed on the peripheral back surface of the display frame 32. Further, since the display 12 is affixed to the housing C with the resin 60, a layer of the resin 60 exists between the back surface of the display window 32 and the display 12. Further, in the portion where the printing frame 30 is printed, a layer corresponding to the printing of the printing frame 30 also exists in the resin 60 layer.

  In addition, a layer of a black mask 26 exists inside the LCD unit 22 and is formed in a lattice shape in the range of the display region 24. Further, a terminal portion 28 is provided at the left end of the substrate 20.

  For example, in the manufacturing process, the resin 60 is applied to the surface of the LCD unit 22 and is in close contact with the back surface of the display window 32. Further, since the resin 60 is a UV curable resin that is cured by irradiating ultraviolet rays, when the ultraviolet rays are irradiated from the surface of the display window 32, the resin 60 is cured and the display 12 is attached to the back surface of the display window 32. Attached.

  In another embodiment, the front cover of the housing C may be formed of tempered glass, and the back surface may be painted so that the printing frame 30 and the display window 32 are formed. Further, the display 12 may be attached to the back surface of the display window 32 by a resin sheet instead of the resin 60.

  5A and 5B are illustrative views showing the positional relationship between the display 12 and the housing C. FIG. In FIG. 5A, the casing C is represented by a dotted line in order to clarify the positional relationship between the display 12 and the casing C. Referring to FIG. 5A, display 12 is attached to the back surface of display window 32 so that LCD unit 22 can be seen from the front surface side of display window 32 of housing C. The area of the display window 32 is slightly larger than the area of the display region 24. Therefore, as shown in FIG. 5B, the entire display area 24 and a part of the black mask 26 can be visually recognized from the surface side of the display window 32.

  Here, the cellular phone 10 is delivered to the manufacturing factory with the display 12 attached to the housing C. However, in the component (assembly component) in which the display 12 is adhered to the casing C, the display component 12 (the display 12 and the front cover) is disposed as a defective product because the appearance of the display 12 is poor if the display 12 is misaligned. In some cases, it is unavoidable.

  However, in this embodiment, since the printing frame 30 having a color similar to that of the black mask 26 is formed on the periphery of the display window 32, the sticking shift becomes inconspicuous, and the number of assembly parts to be disposed of as defective products is reduced. Can be reduced. In particular, since the printing frame 30 is formed on the periphery of the display window 32, vertical and horizontal shifts, rotation shifts, and the like can be made inconspicuous.

  Hereinafter, “lateral deviation”, “vertical deviation”, and “rotational deviation”, which are assumed as deviations in pasting, will be described. Referring to FIG. 6A, when the display 12 is pasted to the housing C while being shifted to the right, the left shift width 40 is larger than the right shift width 42 in the black mask 26 seen from the display window 32. growing. However, as shown in FIG. 6B, when the print frame 30 is shown in the original color (black), the difference between the left shift width 40 and the right shift width 42 is hardly noticed. That is, the lateral shift becomes inconspicuous due to the presence of the print frame 30.

  Next, referring to FIG. 7A, when the display 12 is attached to the housing C while being shifted downward, the upper shift width 44 is shifted downward in the black mask 26 that can be seen from the display window 32. It becomes larger than the width 46. However, as shown in FIG. 7B, when the printing frame 30 is displayed in the original color, the difference between the upper shift width 44 and the lower shift width 46 is hardly noticed. That is, the vertical shift becomes inconspicuous due to the presence of the print frame 30.

  8A, when the display 12 is attached to the housing C while being shifted in the right rotation direction, the upper right shift 48 and the lower right shift in the black mask 26 seen from the display window 32. 50, the lower left shift 52 and the upper left shift 54 are slightly distorted. However, as shown in FIG. 8B, when the printing frame 30 is shown in the original color, each shift hardly becomes a concern. That is, the rotational deviation becomes inconspicuous due to the presence of the printing frame 30.

  As can be understood from the above description, the display window 32 is formed in the casing C of the mobile phone 10, and the LCD unit 22 is attached to the back side of the display window 32. Therefore, the display area 24 is visually recognized through the display window 32. Further, since a black mask 26 is formed on the periphery of the LCD unit 22, a part of the black mask 26 can be seen from the surface of the display window 32. Further, a printing frame 32 is formed on the rear surface of the peripheral edge of the display window 32, and the printing frame 32 is black similar to the color of the black mask 26. For this reason, even if the black mask 26 is looked into from the display window 32 due to a deviation in the attachment of the LCD unit 22, it becomes inconspicuous due to the presence of the printing frame 32.

  By being formed in this way, the shift in attachment becomes inconspicuous due to the presence of the print frame 32, and therefore, it is possible to deal with the shift in attachment of the display 12 at a low cost.

  Note that the width of the printing frame 30 of this embodiment is 0.7 mm, and this width allows a vertical and horizontal deviation width of up to about 0.2 mm, and a rotational deviation of up to ± 0.7 degrees. However, in other examples, it is not limited to these numerical values.

  Further, since the width of the printing frame 30 is 0.7 mm, the influence on the appearance design of the mobile phone 10 is small. That is, the design freedom of the front cover is high.

  Further, examples of colors similar to the black mask 26 include dark gray, dark blue, and dark brown. Further, the brightness difference between the color of the black mask 26 and the color of the printing frame 30 is allowed to 20 or less (minimum value 0, maximum value 255).

  The communication system of the mobile phone 10 is a CDMA system, but an LTE (Long Term Evolution) system, a W-CDMA system, a GSM system, a TDMA system, an FDMA system, a PHS system, or the like may be adopted.

  Further, the shape of the mobile phone 10 is a straight type, but it may be a slide type of two cases or a slide type of three or more cases. Furthermore, the shape of the mobile phone 10 may be a uniaxial folding type, a biaxial folding type, a revolver type, or the like.

  Furthermore, the present invention is not limited to the mobile phone 10 but may be applied to smartphones and PDAs (Personal Digital Assistants).

  The specific numerical values such as the difference in brightness, the length of the width of the printing frame 30, the length of the shift width, and the rotation angle given in this specification are merely examples, and the specifications of the product, etc. It can be appropriately changed as necessary.
